c# - ASP.NET WebAPI HttpGet 操作 - 查询字符串后模型为空

Question

下面的查询字符串没有被 MVC 操作反序列化。操作成功，但我在操作中得到了 searchModel 的空值。

编辑:简化模型

型号

public class EmployeeSearchModel
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

Action :

    [HttpGet]
    public List<Employee> SearchEmployee(EmployeeSearchModel searchModel)
    {
        List<Employee> employees = new List<Employee>();
        try
        {
            if (searchModel != null)
            {
                //some logic
            }
            else
            {
                //dirty feedback for testing - this is what the action returns
                employees.Add(new Employee { FirstName = "searchModel was null" });
            }
        }
        catch (Exception e) { WriteFileLog(_logPath, e.ToString()); }

        return employees;
    }

Answer 1

是 ASP.NET MVC 还是 Web API？从您从 Controller 操作而不是 ActionResult 返回员工列表这一事实，我可以看出它是 Web API。如果是这样，您可以将 [FromUri] 属性应用于模型:

public List<Employee> SearchEmployee([FromUri]EmployeeSearchModel searchModel)
